Couples planning a soup starter or lunch
A 400g tin might be shared or served to one person. Decide how much goes into each bowl before using a half-can or whole-can calorie figure.
Who is this choice for?
Shoppers comparing calories
Per-100g values help compare different tin sizes, but the portion you eat determines the meal total. Check salt separately rather than treating a low-fat label as a summary of the nutrition panel.
People buying for different dietary needs
Check the exact tin’s ingredients, allergen statement and vegetarian or vegan designation. A familiar flavour name does not establish whether a soup suits the person you are serving.
What should you compare?
For a Valentine’s Day starter, choose the amount each person will have before comparing tins. Then check the nutrition and ingredients for that serving, including anything you plan to add.
| Priority | What to check | Your needs |
|---|---|---|
| Portion calories | Compare kcal per 100g, then check the stated serving weight and tin size. Tesco Groceries lists its 400g Low Fat Tomato Soup at 61 kcal per 200g half-can; two such portions total 122 kcal. | Are we sharing one tin as a starter, or will each person have a whole tin? I want the calorie figure to match what goes into each bowl. |
| Salt | Read salt in grams for the planned serving as well as calories. Tesco Groceries lists 0.69g per 200g portion of its Low Fat Tomato Soup; its listing for the 295g Heinz Weight Watchers Chicken Soup gives 1.9g per can. | A lower-calorie option still needs a separate salt check, particularly if I am comparing a half-can portion with a whole can. |
| Ingredients | Read the current pack’s ingredients, allergen statement and any vegetarian or vegan designation. Check the exact variety rather than relying on words such as tomato, vegetable or creamy. | If I am serving someone else, I need to know whether this particular tin meets their dietary requirements. |
| Preparation and extras | Check whether the soup is ready to heat or condensed. Follow its dilution directions and consider milk, bread or toppings as separate parts of the meal. | I may serve soup with bread or add something to the bowl, so the soup’s label alone will not describe everything we eat. |
What can change the meal total?

Reading a half-can figure as a whole-can figure
Tesco Groceries lists 61 kcal per 200g half-can of Low Fat Tomato Soup and 87 kcal per 200g half-can of Low Fat Lentil & Vegetable Soup. Eating either entire 400g tin means having two labelled portions.
Decide how the tin will be divided, then use the labelled portion weight to work out the amount each person will have.
-
Letting a low-fat label stand in for a salt check
Calories and salt answer different questions. Tesco Groceries lists Heinz Weight Watchers Chicken Soup at 92 kcal and 1.9g salt per 295g can.
Compare salt for the amount you will eat, using the numeric label alongside any traffic-light labelling on the pack.
-
Comparing condensed soup with a ready-to-heat tin as served
Preparation changes the final bowl. Joybuy’s directions for Campbell’s Condensed Cream of Chicken Soup specify dilution with water, or with half milk and half water, before heating.
Follow the directions for the exact tin and consider the ingredients you add when comparing prepared servings.
Choosing milk instead of water adds another ingredient to the prepared soup.
-
Assuming a flavour tells you who can eat it
Recipes and allergen declarations differ between varieties, including soups with similar-sounding names. That matters when the meal is for someone whose dietary requirements you need to accommodate.
Read the ingredients and allergen statement on the current tin before buying or serving it.
Brand and product references
These examples show why the exact variety and serving size matter; their figures do not describe every soup from the same brand.
Tesco
Tesco Groceries provides both per-100g and half-can values for its Low Fat Tomato Soup and Low Fat Lentil & Vegetable Soup.
- The tomato soup is listed at 61 kcal per 200g half-can; the lentil-and-vegetable soup is listed at 87 kcal per 200g half-can.
- Those half-can figures are not whole-can totals. Check the current pack before serving.
Heinz
The Tesco Groceries listing for Heinz Weight Watchers Chicken Soup gives nutrition for its 295g can.
- The listing states 92 kcal per can, avoiding a half-can calculation if one person eats the tin.
- It also states 1.9g salt per can, so its calorie figure should not replace a salt comparison.
Campbell’s
Campbell’s Soup UK presents Cream of Chicken Condensed Soup as a product prepared with added liquid.
- Its UK product information lists 96 kcal and 0.86g salt per 100g as consumed.
- Use the preparation instructions for the exact tin when assessing a served bowl; a condensed soup is not a like-for-like serving comparison with an undiluted ready-to-heat tin.
M&S
M&S lists product-specific nutrition and dietary information for its tinned soups.
- Its Chunky Mexican-style Chilli and Bean Soup is labelled vegan and vegetarian, with 62 kcal and 0.50g salt per 100g.
- Those values and designations belong to that variety; check the pack of any other M&S soup individually.
Tinned soup options on Joybuy
These options include savoury soups for a starter or lunch and a sweet soup that may suit dessert instead. Use each tin’s current label to compare the portion you plan to serve.

Heinz Cream of Mushroom Soup 400g
For a shared mushroom soup starter, decide how much of the 400g tin each person will have. Check the current pack’s portion figures and ingredients, particularly if milk or wheat needs to be avoided.

Crosse & Blackwell Best of British Spicy Parsnip & Carrot Soup 400g
This parsnip-and-carrot soup is a savoury option for a starter. Check the 400g tin’s serving guidance before comparing bowl-sized portions, and read its ingredient and allergen statement if celery, milk or wheat matters to your choice.

Itoen Special Rich Corn Potage Soup 185g
The 185g can offers a different size to the 400g savoury tins. Read its current nutrition panel to compare calories and salt for the amount served, and check the ingredients if milk or chicken is unsuitable.

Bestore Stewed Snow Fungus Soup 200g
This is a sweet, dessert-style soup rather than a substitute for a savoury lunch starter. If serving it for dessert, use the 200g tin size and current nutrition panel to work out each portion, and check the pack’s ingredients and allergen statement.
Questions about choosing and serving soup
Should I compare calories per 100g or per tin?
Use per 100g to compare different products, then use the serving or tin figure for what you will eat. Tesco Groceries lists Low Fat Tomato Soup at 61 kcal per 200g half-can, so two labelled portions amount to 122 kcal for the 400g tin.
Does a lower-calorie soup necessarily contain less salt?
No. The Tesco Groceries listing for Heinz Weight Watchers Chicken Soup gives 92 kcal and 1.9g salt for the same 295g can. Read both values for your planned portion rather than using calories to judge salt.
How do I compare a 400g tin when serving soup for two?
Check whether the label’s serving is half the tin, then decide whether each person will have that amount. Tesco Groceries lists its 400g Low Fat Tomato Soup at 61 kcal per 200g half-can and its 400g Low Fat Lentil & Vegetable Soup at 87 kcal per 200g half-can.
Can I tell whether a soup is vegetarian or allergen-suitable from its flavour?
No. Check the designation, ingredients and allergen statement for the exact tin you will serve. For example, M&S labels its Chunky Mexican-style Chilli and Bean Soup vegan and vegetarian, but that designation does not apply to other varieties simply because they contain vegetables.
What should I do with soup left after opening a tin?
Follow the storage directions on that tin. M&S directs shoppers to transfer leftover Cream of Tomato Soup to an airtight container, refrigerate it and eat it within two days; Joybuy’s directions for Campbell’s Condensed Cream of Chicken Soup also specify a covered container, refrigeration and use within two days.
